SIGN.

Application filed mm a, 1925. Serial no. men.

This invention relates to signs. The general object of the invention isto provide a sign which is constructed so that the entire si n islighter in weight than the 6 weight of the air it displaces so that thesign will be suspended in elevated positlon. One of the specific objectsof the invention is to provide a sign which may consist of one or morehollow characters made of light wei ht material and inflated with alight gas so it vated position.

Another ob'ect of the invention is to provide a si w rein the charactersare made i 1 from he ow tubes of flexible material filled with gas.

A further object of the invention is to provide a sign comprising aframe con- I structed of light material and having elon- 20 gated rubbertubes therein formed to simulate charactersand wherein the tubes. are

inflated to hold them in distended position.

Other objects of the invention will be apparent from the followingdescription taken in connection with the accompanyin drawings whereinFig. 1 is an elevation o a sign embodying the features of my inventionFig. 2 is a top plan view of the sign; Fig.

3 is a perspective view showing a modified 0 means or supporting thesign; Fi 4 is an elevation showin a further mod ed form of support andig. 5 is a top plan view of one of the elements of which the sign isconstructed.

3 Referrin to the drawings by reference characters, have shown a signembodying the features of my invention at 10. The

sign may be constructed in any desired manner and in the followingdescription al- 49 though I refer to letters and numerals, I

wish it to be understood that my invention may be embodied in variousways other than by letters and numerals, if desired.

For instance, a character which is used as a trade mark may be employedas the figure of the sign.

Referring again to the drawings, it will be seen that the sign as showncomprises a frame 11 consisting of longitudinal members and transversemembers. The frame as shown in Fig. 1 comprises an upper member and alower member which may be sepat the sign will be maintained in ele-.

ng} an inflating nipple 15 thereon.

.19 y means of a cord which engages arately made and ingmembers 12.

The frames 11 are preferabl made of bamboo or other light wood or. eymay be made of aluminum or other light weight metal. I v

The frames comprise a polygonal bod within which the characters 14 aresecur Each of the characters as illustrated comprise a hollow tubularbody preferably constructed of rubber or other material and havmay beunited by fastenach character is made from one or more of thetubular-bodies 14 and these tubular bodies are held in the properposition to form the desired characters by means of strings 16 which aresecured to the frame 1n a suitable manner to in their proper position.

In the sign I have shown the word Rogen as on the top line and beneathit the numerals 57 although any desired characters may be used.

The bodies are preferabl filled with hydrogen, hehum, or other reatively li ht gas so that the whole framework will In: suspended in theair.

I prefer to cover the sustaining tubular bodies with phosphoric aint asshown at 18.

The sign may be hel in position in any desired manner. In Fig. 1 it isshown as sup rted on a flag pole or other support an eye 21 on the sign.

In Fig. 3 the sign'is supported at the bottom by cords 25, while theupper portion of the sign is held against undue swa ing by cords 26. InFig. 4 the sign is he d by a cord 27 which holds the sign in thelrlnsiidmer similar to that in which a kite is In addition to thefastening members 12 the ends may be braced by strips 30 if desired.

Having thus described my invention, I claim:

In a sign, a supporting member comprising a relatively light framecomprising longitudinal members and transverse members united to andholding said longitudinal members in applied apart relation, charactersarranged m an upon said frame, said hold the characters 79 Q Lee-ewecharacters being formed. by hollow tulmlai ing the normally straighthollow tubular bodies, said bodiee containing a, fluidi oi lbolliee 11mlattachfl to saidfmme in such lighter than air density, said hollow'lmlmlai a manner as to form said stmi ht hollow 10 bodies when freefrom said frame being tubular bodies into the desired 0 araoter. 5straight and means for forming sairl hollow In testimony whereof, Ihereunto aflix my tubular bodies into the form of saicl ohorsignature.
